Teenage boys beware: That girl you're chatting to on Facebook could be a man—it could even be a 400-pound, 6-foot-3 police Florida officer like Sgt. Michael Stavris. Authorities say the officer posed as a teenage girl online, promising teen boys oral sex in return for pictures of their penises, the New York Daily News reports. Stavris, 30, has been charged with two counts of violating the Computer Pornography and Child Exploitation Prevention Act and faces up to five years in prison if convicted, reports the St. Augustine Record. Police say he had been under investigation for more than a year and had befriended around 40 students under 18 with his fake Facebook profile.
